This invention relates `to attachments for spectacles. 1 rc; 1 Jewelersand others in the habit of usin magnifying-glasses ofthe type fitted tothe eyes have heretofore been placed at a disadvantage if spectacles areworn, because it has been necessary to remove the spectacles in i orderto place the `magnifying glasses in y. proper position over 'theeyes,.this removal of j the spectacles obviously impairing the vision.Theobject of this invention is to provide a magnifying-glass whichconstitutes an atzo' tachinentfor spectacles and whichcan be quicklyswung into oroutof proper position.

A still furtherobject is to provide an attachmentcapable of beingadjusted to the leye of the user. s` With'the aboveandv other objectsinview the invention consists'of-a clamp of novel form adapted to befastened to spectacles at the point of connection-.between a rim and oneof the temples. A stem projects for- 3o ward from the clamp, andadjustably mounted upon this stem is an armprojecting from an auxiliaryvrim containing a magnifyingglass. vMeans are provided for supportingthis glass directly in front of one of the lenses of the spectacles andfor supporting the glass 1n raisedposition, so as not to interfere withthe vision.

ytacles', showing the magnifying-glass provided with a modiiied form ofconnecting device.l Fig. 7 is a section through thel clamp, stop, andthe connecting device. Fig. 8 is a similar section, showing a modifiedmeans for stopping or limiting the movement of the magnifying-glass, andFig. 9 is a detail view ofthe modified meansy utilized for connectingthe magnifying glass to the stem of the clamp.

Referring to the figures by characters ofA reference, 1 is the frame ofa pairofspectacles, `having ears 2 extending from the ends thereof inthe usual manner and constituting bearings for temples 3, mounted onpivotscrews 4. Bearing uv on thefront face of the ear at one end of t eframe 1 is a plate 5,

kthrough the ends of which extend the threaded ends of a yoke4 6, whichembraces the ear and has nuts 7 for clamping plate'5 rmly upon the ear.An extension 8 projects from the outer edge of the plate 5 at an anglethereto and has parallel ears 9, which eml brace the ear 2 and, inconjunction with the yoke 6, serves to positively hold plate 5 immovablyupon the frame. A screw-threaded stem 10 extends forward from plate 5,and a nut 11 is adjustably mounted thereon. A clamping-nut 12 is alsolocated yon the stem, and interposed'between the two nuts is a Washer13, having a laterally extending curved projection y14, constituting astop and Y partly surrounding the nut 11 and a portion of the stem 10. Anut 15 is mounted on the stem between frame -1 and nut 11', and this nutis permanently secured to the center of one side of alongitudinally-slotted arm 16. To the'center of the other side of thisarm is permanently secured a rim 17, surrounding a lmagnifying-glass 18.The projection 14 is adapted to be adjusted about the stem 10, so as tocontact with the lower portion of arm 16 and support the glass 18directly in v 19 of the spectacles. After the projection has beenadjusted to this position the outer nut 12'is screwed .against thewasher 13, so as to clamp it upon the nut 11. The projection will thusbe immovably secured, and it is of such proportions that when the glass18 is swung upward 10 and rest by gravity upon the, lupper'portion ofprojection 14. It will thus be seen that the glass 18 can be quicklythrown into or out of operative position.

If deslred, instead of utilizing the slotted lOO IIO

arm 16 a sleeve 2O may be arranged upon a nut 21 on stem l() and receivea threaded stem 22, extending radially from the frame 23 of themagnifying-glass. A nut 24 is disposed upon the stem 22, and with thisconstruction the magnifying-glass can be adjusted laterally in order toassume a proper position in front of the eye.

In lieu of utilizing the stop or projection 14 the nut to which themagnifying-glass is connected may be arranged between two stopnuts 25,mounted on the stein and adapted to limit the rotation of theglass-carrying nut 26, so that the glass can be swung into or out ofoperative position, but will be pro erly limited during such movement.here these stop-nuts 25 are employed, lock-nuts 27 are preferablyutilized for holding them in j adjusted position.

It will be seen that this attachment can be readily applied to variousforms of spectacles and the magnifying glass can be easily 'moved intoor out of operative position.

While the attachment is particularly adapted for use in connection withspectacles such as constantly worn by some jewelers and others whosebusiness requires the use of magnifying-glasses, it is to be understoodthat spectacles Without lenses or with lenses with plain glass can beused merely as a means for holding the magnifying-glass in properposition before the eye and without effort on the part of the user.

The preferred form of the invention has been set forth in the foregoingdescription; but I do not limit myself thereto, as I am aware thatmodifications may be made therein without departing from the spirit orsacrificing the advantages thereof, and I therefore reserve the right tomake such changes as fairly fall within the scope of the invention.

What is claimed is- 1. An attachment for spectacles comprising a plate,means for clamping the same upon the frame of spectacles, ascrew-threaded stem projecting from the plate, rotatable meansadjustably mounted upon the stem, a glass carried thereby, and means onthe stem for limiting the movement of the rotatable means and supportingthe glass.-

2. An attachment for spectacles comprising a clamp, a screw-threadedstem projecting therefrom, a rotatable device adjustably mounted on thestem, a glass adjustably connected to said device, and means forlimitingr the movement of the rotatable device and supporting the glass.

3. rl`he combination with spectacles; of a clamp secured to one end ofthe frames thereof, a forwardly-projecting stem upon the clamp, larotatable device adjustably mounted on the stem, a sleeve carriedthereby, a glass, a stem connected thereto and adjustably mounted withinthe sleeve, and means for supporting the glass in, or out of, alinementwith a lens of the spectacles.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
